A rapid plant survey was conducted in around the proposed Cheyyur 4000MW Ultra Mega Power Project in Kanchipuram District, Tamil Nadu. The surveys were conducted along Vilambur, Buckingham Canal, Vanjimodu and the Palaiyur Reserve Forest within the project site and the portion of Palaiyur R.F.

In this paper, we look into the relationship that exist between four tribal communities viz. the Kondh, Poraja, Gadaba and Bonda of the Koraput region with their natural resources. Eucalyptus globulus Labill., when introduced into the tribal ecosystem is rejected by the community and so is Acacia auriculiformis A.Cunn ex Benth., while another tree Pterospermum acerifolium Willd. when introduced is readily accepted by the community. A new water reservoir makes fish readily available to the community and the community incorporates the new resource into their culture.
